User Registration Fails Due to Supabase Email Rate Limiting and Unhandled Signup Errors

[sumit90asa-coder]

Description

The signup flow fails when creating a new account because requests to the Supabase authentication endpoint are returning 400 Bad Request and 429 Too Many Requests responses.

Users are shown the message:

"email rate limit exceeded"

which prevents successful account creation.

The application currently exposes backend rate-limit errors directly to users without providing clear guidance or recovery options.

Steps to Reproduce

1. Open the application.
2. Navigate to the Sign Up page.
3. Enter valid registration details.
4. Click "Create Account".
5. Open Developer Tools (F12) and check the Console tab.

Actual Behavior

The following requests fail:

POST /auth/v1/signup → 400 Bad Request
POST /auth/v1/signup → 429 Too Many Requests
